The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; show every role.

We review the physics assumptions and input used in ISAJET~7.0 / ISA\-SUSY~1.0 that are relevant for simulating fundamental processes within the framework of the Minimal Supersymmetric Standard Model (MSSM) at $p\bar p$ and $pp$ colliders. After a brief discussion of the underlying MSSM framework, we discuss event simulation and list the sparticle production processes and decay modes that have been incorporated into our calculations. We then describe how to set up and run an ISAJET / ISASUSY job and the user input and output formats. The ISAJET program is sufficiently flexible that some non-minimal supersymmetry scenarios may be simulated as well. Finally, plans for future upgrades which include the extension to $e^+ e^-$ collisions, are listed.

Original abstract

We review the physics assumptions and input used in ISAJET~7.0 / ISA\-SUSY~1.0 that are relevant for simulating fundamental processes within the framework of the Minimal Supersymmetric Standard Model (MSSM) at $p\bar p$ and $pp$ colliders. After a brief discussion of the underlying MSSM framework, we discuss event simulation and list the sparticle production processes and decay modes that have been incorporated into our calculations. We then describe how to set up and run an ISAJET / ISASUSY job and the user input and output formats. The ISAJET program is sufficiently flexible that some non-minimal supersymmetry scenarios may be simulated as well. Finally, plans for future upgrades which include the extension to $e^+ e^-$ collisions, are listed.

Stability of the CMSSM against sfermion VEVs
hep-ph 2013-09 conditional novelty 5.0 of 10

In the constrained MSSM, parameter regions with light staus or light stops are mostly metastable against tunneling to charge- and color-breaking vacua, and the widely used analytic stability conditions fail to detect this.
Radiative natural supersymmetry: Reconciling electroweak fine-tuning and the Higgs boson mass
hep-ph 2012-12 conditional novelty 5.0 of 10

A non-universal Higgs mass MSSM region with large top-squark mixing can reach 3 to 10 percent electroweak fine-tuning while yielding a 125 GeV Higgs and TeV-scale stops.

After LHC7 sparticle limits and a 125 GeV Higgs, the surviving mSUGRA/CMSSM parameter space requires at least 0.1 percent fine-tuning by a high-scale measure and 1 percent by a weak-scale measure.
